Regrettably, too many homeowners make expensive mistakes during the process, believing a simple patch or coat of waterproof paint will solve the problem. Be it Columbia or any place with heavy rains and storms, avoiding common waterproofing mistakes can save thousands.
Let’s explore the biggest waterproofing mistakes and how to dodge them step-by-step.

? Always install a backup for your sump pump.

Common issues include:

Solutions include:

What works better:
? Professional-grade barrier systems
? Baseboard or perimeter channels
? Sump pump setups

Mistake #3: Not Addressing Foundation Cracks
Minor cracks may seem safe, but horizontal or expanding ones aren’t. DIY kits might seal visible gaps—but not solve the cause.
Fix them by:
? Getting a professional assessment
? Applying polyurethane-based sealants
? Adding relief systems to prevent pressure buildup
Mistake #4: Attempting Waterproofing Without Experience
Trying to waterproof yourself without knowing the risks. Many mistakes happen:
? Skipping prep
? Installing systems without inspection
? Addressing symptoms, not the cause
